I was going to ask for a screenshot of the hung state and ask you to check the server was configured to boot from the network first, then look at your http connection to the pxe server, but... I see from your case #17331, and the related case #17241 that you've probably had all that from support already, and you're having a serious issue with the %POST section of your kickstart file.

Have you tried pasting the whole of your original kickstart file into the space for additional kickstart options? Anything placed in there overrides the GUI portion of the system package.

It seems that anything placed in into the space for additional kickstart options does not overrides the GUI portion of the system package, but create new sections in the kickstart file generated, and so duplicate sections like %package and %post.

That's why it is not easy yet to make a workaround to correct the Grub problem.

wiping the MBR in this case will not help. what olivier is hitting is a functionality issue with how we do the "%post" section of the post os install script. we create a script that gets executed during the boot process that happens immediately following the OS install. additionally, the customer provides two post sections in their typical system package, one which is a regular "%post" and another which is "%post --nochroot". the nochroot one can be forced into the package by inserting the "%post --nochroot" into the post os install script at the end. this will result in two "%post" sections being created. he needs this to run, however, before the system reboots and not during the startup process. this is where the enhancement requests have to come into play...

I have closed the ticket nbr 17331 related specifically on the Grub problem, because this problem is solved by provisioning Red Hat Enterprise Linux 4 Update 5.

Thanks to Sean Berry for the info, he was right. BladeLogic is only able to provision Red Hat Enterprise Linux 4 Update 4 or higher.

No more problems with GRUB loader.

Nevertheless, I let opened the other ticket nbr 17241 related to the Red Hat Enterprise Linux 4 kickstart post-installation process, which would technically be addressed by enhancement request nbr 17701.
